Application filed November in lieu of the pneumatic or solid rubber type of tire.

The primary object ofthis invention resides in the provision of such a tire that may be readily assembled and applied to wheels of variousconstructions and. that will afiord as relatively easy riding qualities for the vehicle as is'now secured by the use of pneu- 7 upon the line matic or solid rubber tires and this without "the consequent liabilityof the tire becoming punctured or otherwise disrupted necessitating the application of other tires while the vehicle is upon the road- A further and important object of the invention is to: substantially improve and simplify over similar constructions previously used and patented.

I With the foregoing and other objects in View as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts hereinafter more fully described and shown in the accompanying drawing and claimed.

In the drawing wherein like reference characters designate corresponding parts throughout the several views v V Figure 1 is a view partly in elevation and partly in cross section of my improved tire.

Fig.

tially upon the line 2-2 of Fig. 1, and

Fig. 3 is a similar view taken substantially 33 of the .same'figure. Now having particular reference to the drawing wherein the novel tire constitutes theprovision of an inner and outer rim 5 and 6 respectively arranged in concentric springs relation as per Flgs. 5 is formed internally at predetermined spaced points with pendantears '7 attheopposite ends of which are openings 8 within which arev secured certain ends of coil 9-9 that extend in converging relation and have their opposite ends adequately secured as at 10-10 to lugs 1111 that are formed upon the exterior surface of the inner rim 6 opposite the respective ends of the outer rim ear obviously serve as a means'for preventing the entire outer displacement of the inner and outer rims with respect to each other.

As will be obvious, sets of the springs 2 is a detail section taken substansidered in'conjunction with the accompany-v ing drawing, it is believedby me that the V advantages and operation of a spring wheel of this character will be-readily apparent to those skilled in the art, and even though 7 I have'herein shown and described themost 2 and 3. The outer rim 7, Fig. 1. These springs 1. 9-9 are provide-deedintermediate two adjacent sets thereof is a generally U-shap ed leaf spring '12, the legs of'which extend outwardly and diverge m relatlon and are overtional contact with the interior surface of the outer rim 5, Fig. '1.; These springs 12 are'rigidly connected as at 14 through the inner rim 6 and serve as a medium for main.

with respect to each other and also for forcing the rim 5 outwardly of the rim *6 at. points of unengagement of-the outer rim turned at their outer ends as at 13 for frictend to alined openings in the'pla-t'es and ears 19 formed at predetermined spaced points on the flanges 15- 15.

The outer surface of the rim 5 may so formed as to receive a solid rubber band for I increasing the traction properties of the out er rim, but I do not desire to be limited to the use of such a band. v

From the foregoing description when conpreferred embodiment of'the invention with which I am at this time familiar, it is neveri thelessto be understood that minor changes may be made therein without departing from the spirit and scope of the appended claim.

Having thus describedniy invention, what I clalm as new and desire to secure by Let- V the outer rim member and slidably contacte5 taining the rims in proper spaced relation ing the flanges on the inner rim member and forming an annular chamber between the rims and rings, and a plurality of circumferentially spaced ears carried by the inner periphery 'ofthe outer ri1n,' a plurality of pairs of lugs carried by the outer periphery of the inner rim, the ears being disposed at points between the pairs of lugs, sets of coiled springs, each set being connected With j a pair of lugs and an adjacent ear, and a 0 the inner rim, the extremities of the arms of said members being curved and bearing slidably againstthe inner periphery of said '15 outer rim.
